1. Eat Less Added Sugar

“Sugar leads to insulin spikes which can cause fat storage—especially around the middle. Try to eat less of it.” — Dianne Rishikof, MS, RDN, LDN, IFNCP

Eat This! Tip

Unfortunately, our labeling laws haven't quite caught up to our dietary guidelines, and food products don't yet have a column dedicated to added sugars. Instead, the naturally occurring sugars and the added stuff are all clumped together under "sugar." This is particularly confusing when you're buying things like flavored yogurt, which contain both types of the sweet stuff. So when in doubt, read the ingredients list. If you see words like sugar, honey, agave, or even organic cane juice, know that there's added sugar in your food. To find out how much, look at a similar, unflavored version of the product you're interested in buying and see how they differ. For example, if a serving of plain oatmeal has 1 gram of sugar and a flavored version has 16, it's safe to assume you'd be consuming 15 grams of added sugar. When it comes to candy and sweets, assume all of it's the added variety. For more ways to eat less of the sweet stuff, order your copy of the Zero Sugar Diet today!

3. Hit the Weights

“Strength training is a must over 40. It builds lean muscle mass, which, over time, will help boost your resting metabolic rate which slowly declines with age. So long as you have good form and proper coaching, don't be afraid to lift heavier weights than you have in the past. — Jennifer Cassetta, clinical nutritionist, personal trainer, and health expert from ABC's "My Diet Is Better Than Yours"

4. Be Patient

“For many women in their 20s, it’s relatively easy to drop 10 pounds by cutting back on calories for a few weeks. But as you age, your metabolism slows, so what worked in your 20s may no longer be effective. The trick is to stay the course and be patient. Eventually, the scale will drop.” — Martha McKittrick, RD of Martha McKittrick Nutrition and City Girl Bites

5. Dial Back on Cardio

“Don’t overdo it with the cardio. Spinning up the wazoo isn’t going to give you the results you want. Declining estrogen leads to declining muscle mass which leads to declining metabolism. While that sounds depressing, there’s an easy solution: weight-bearing work. If traditional weight lifting isn’t your thing, try barre classes and pilates.” — Lauren Slayton, MS, RD, of Foodtrainers

6. Nix Processed Carbs

“Cutting back on processed carbohydrates is essential for weight loss after 40. Maintaining blood sugar and insulin levels is vital to weight loss, so cutting back on foods that spike blood sugar and insulin is a must. Any foods that contain added sugars, as well as foods that quickly break down into blood sugar, should be reduced. These include white bread and pasta, baked goods, cereal, candy, sweetened drinks, chips, and conventional crackers.” — Jennifer Cassetta, clinical nutritionist, personal trainer and health expert from ABC's "My Diet Is Better Than Yours"

7. Start your day with protein instead of carbs

“Starting your day with protein instead of carbs prevents blood sugar spikes and insulin activity (our fat-storage hormone). It also prevents bloating. Ditch the cereal and toast and start your day with two hard-boiled eggs, a protein shake, a veggie omelet, or a Greek yogurt with chia seeds and berries, instead.” — Amy Shapiro MS, RD, CDN of Real Nutrition NYC

9. Eliminate Foods that Bloat

“Consider taking out foods that cause bloat, including dairy products. As we age, our bodies can't break down lactose as efficiently. When we can’t efficiently digest something, it tends to cause gas and bloat, which is the opposite of a flat stomach. Avoid dairy foods, and you’ll likely see some improvement!” — Amy Shapiro MS, RD, CDN of Real Nutrition NYC

10. Stop Doing Crunches

“It's no exaggeration to say at 47, I look far better in the midsection area than I did at 27. It's not about the crunches or even the planks. I firmly believe that a flat belly is a result of cardio and a wholesome diet.” — Carla Birnberg, personal trainer and fitness blogger

11. Stop Pursuing Weightloss

“No diets work long-term. Not to mention, weight loss diets typically promote disease, not health. We are not supposed to look like we did when we were in high school. As women, we need to respect that our body changes throughout life to support our needs. Fighting our body promotes negative body image and disease.” —Julie Duffy Dillon MS, RD, NCC, LDN, CEDRD

12. Stay Away from Salt

“Stay away from the salt. Too much sodium in the diet contributes to edema and bloating, and seems to affect us more as we age. So if you have to zip up a pencil dress or wear your 'fitted' suit, I recommend consuming no more than 1,500 milligrams of salt per day. Avoid ready-made meals and canned foods, which are loaded with salt. And when you’re at restaurants, simply ask for no or little salt in your food. Small changes can make big changes to your waistline.” — Amanda Russell, certified personal trainer and YouTube fitness star

13. Identify Your Why

“Pause and identify your why. Anything from a high school reunion to a beach vacation is reason enough to want to get in shape! Just be certain that your motivator is something that motivates you enough to sustain forward momentum on those days when you'd rather slack. — Carla Birnberg, personal trainer and fitness blogger

14. Consume More Omega-3s

“Many types of healthy fats can help you lose body fat. Omega-3s are one type with these superpowers. Try to have one omega-3 rich food every day. Eggs, fatty fish, chia seeds and walnuts are some good options.” — Lauren Slayton, MS, RD, of Foodtrainers

15. Prioritize Sleep

“In your 20s, you can get away with late nights and minimal sleep. But in your 40s, your body doesn’t rebound as well. Getting too little sleep will hit you hard the next day. You’ll likely have less motivation to exercise and have increased hunger for fat and carbs. — Martha McKittrick, RD, of Martha McKittrick Nutrition and City Girl Bites

16. Stop Calorie Counting

“Restricting your caloric intake will only backfire. Instead, focus on food quality over quantity. Consume a balance of protein, low-glycemic carbohydrates, and healthy fats like avocado, nuts, nut butter, seeds, and olive oil. This balance of macronutrients will help to keep you full, while also maintaining blood sugar levels. Also, be sure to partake in moderate exercise and get adequate sleep.” — Susan Stalte, RD, LDN, MBA-Candidate

17. Make Small Changes

“Stop thinking of weight loss as a grand process and, instead, think of it as a series of small daily commitments. To fit more activity into your day, play with your children or take the stairs instead of the elevator. Once you’ve committed to these small changes, the easier it'll be to advance to the bigger workouts that can lead to a flat belly.” —Rick Richey, NASM-CPT, CES, PES, owner of the Independent Training Spot

18. Don’t Deprive Yourself

“Swap calorie-loaded indulgences like ice cream for blended frozen fruits or lightened up, decadent-tasting desserts like Halo Top. Halo Top has just 60 to 90 calories a serving, 6 grams of protein, and 3 grams of fiber which work together to keep blood sugar stable so that you won't crave more sugar. This simple swap will save you calories and help you lose the belly fat.” —The Nutrition Twins, Tammy Lakatos Shames, RDN, CDN, CFT&Lyssie Lakatos, RDN, CDN, CFT

Eat This! Tip

Can’t find Halo Top in your area? Buy a pint (or three!) online at Amazon.com (from $5.49) or IceCreamSource.com ($6.99). The ice cream will be shipped to your front door on dry ice.

19. Move Every Day

“Before you groan at the thought of hitting the treadmill every day, hear me out! Performing any type of exercise that gets your heart rate up and blood flowing will keep your metabolism going and fat burning. This can be as simple as waking up earlier and going for a 30-minute walk or incorporating a 10-minute interval workout in your living room. (Here is one I like to do: HIIT Total Body 12 Min Workout.) Whatever it is, make sure to get your heart rate pumping at least once a day to help burn fat and get lean.” — Amanda Russell, certified personal trainer and YouTube fitness star

20. Add Veggies to Every Meal

“No matter what you’re eating, mix it or serve it with vegetables. Having Chinese or Italian takeout? Making a stir-fry, burrito, or fajita at home? Split the dish in half, saving the other half for another meal, and mix in at least 1.5 cups of steamed vegetables right into your meal. Not only will you eat less of the heavier fare and slash the calories nearly in half, but you’ll also have a second serving for another day.” —The Nutrition Twins, Tammy Lakatos Shames, RDN, CDN, CFT&Lyssie Lakatos, RDN, CDN, CFT

21. Manage Your Stress

“Have a mindfulness practice. Stress can be overwhelming in your 40s. Whether you have small children, a consuming career, or both, you’re most likely busy taking care of other people and have less time for yourself. Try meditation, yoga, Tai Chi, or breathing exercises to bring down stress hormone levels like adrenaline and cortisol, which can trigger fat storage.” —Jennifer Cassetta
